Intro: How to assemble a HHO Generator and why it works
How an HHO generator works and helps you save gas
An HHO or Brown gas generator is an interesting and often misunderstood technology.
The Brown gas generator uses electrolysis to split water (H2O) into it´s base molecules, 2 hydrogen and 1 oxygen molecule.
This is why it is often referred to as an HHO gas generator.The HHO in itself is not an alternative to gasoline but a additive
to boost the efficiency of the engine. Gasoline engines are unfortunately not burning gasoline to its full potential. See http://en.wikipedia.org/wiki/Engine_efficiency
The average gasoline engine in a car is about 18% to 20% efficient. That leaves a lot of room for improvement and Brown gas is one good way of improving the
efficiency. The reason for this is simple, the hydrogen is highly flammable much more so than gasoline so when your engine ignites the hydrogen the explosion ignites
the gasoline with much better results (cleaner, less waste and fewer emissions) than it would otherwise have done.

Step 2: The Brown Generator
I modified the Brown generator I bought on ebay by adding connections to the places and replacing the spacers with smaller ones to increase the surface area.
You will have to buy bottled water because tap water can have metal in it that will rust the plates.
You will also have to ad an electrolyte to the water to speed up the electrolysis.
The highest production of hydrogen occurs with the plate polarity alternate as in +-+-+.( It also consumes the most amount of electricity)

Step 3: Pulse width modulator
Is an important tool to control the electrolysis. A simple generator can be built without PWM but that is like having an engine with only the possibility of full throttle or no
throttle at all. The pulse width modulator is necessary for a controlled electrolysis. The specific frequency and power for the most efficient electrolysis wares form
generator to generator.
You will have to fine tune the PWM your self but that is simple. You just fine tune the frequency first, by tuning the frequency up until the bubbles from the electrolysis
plates start decreasing after you hit maximum bubbles and then go back to the best setting (producing the most
amount of bubbles) and then do the same for the power setting. It is best to get a powerful PWM at least 35 Amps preferably more.
I use a 50 Amp PWM and a LCD Display from canakit. http://www.canakit.com/50a-dc-pwm-motor-speed-controller.html

Step 4: EFIE
EFIE (Electronic Fuel Injection Enhancer)
The EFIE is intercepting signals from the oxygen sensor to the computer and fools the computer by giving it false exhaust readings from the Oxygen sensor.This is
necessary because the computer is set up for a regular burn of fuel and compensates for the more efficient and cleaner burn by dumping more gasoline into the engine
(until it gets the reading it expects) which ruins your fuel savings.
Gasoline burns better (cleaner less waste) with HHO gas because the increase burn temperature .
You can buy a EFIE on the internet or if you have the skills you can build one.

Step 5: Installation
I made a hole for the wires from the PWM to the Brown generator along side the existing electric cables,
the I put a peace of metal (with rubber on one side) around the Brown generator and screwed it to the frame of the car.
I drilled a hole in the air intake behind the air filter and inserted the air connector. I then put one way air valve on the hose
and connected the Brown generator to the engine.
Then I lengthen the cables of the PWM, thunk the variable resistors out and attached them til long wires, I also mad an manual on-off
switch extension. I then used the glue gun to glue the PWM to the top of the small glove box under my steering while,connected the wires slid the glove box into place
and then glued the variable resistors and the LCD Display in the small hatch where the fuses are.
It is all easily accessible bot not visible.

Because the title is "How to assemble a HHO Generator and why it works" I failed to find the explanation of the second part - why it works. Did you forget to
add it? Then you should expand your instructable.

It is not Brown gas. It is sometimes known as "Brown's Gas". Named after Yull Brown who advocated it. http://en.wikipedia.org/wiki/Oxyhydrogen
What are your actual results?
I've been working on a similar rig. So far I've been able to run a Briggs and Stratton motor on it briefly.

Doesn't it take quite a bit of energy to separate water into Brown Gas? I don't believe anything comes free in this world, and if Brown Gas had such great
potential, it would be used all over the place by now, since this is far from a 'recent' discovery. You put more energy into making Brown Gas, than you get
back out of it. The boost in MPG, isn't any different, than say properly maintaining and tuning your vehicle, or changing your driving habits. But, it is nice
to dream, and everyone needs a hobby or two.

As you took the time to link to the Wikipedia article that discusses the efficiency of ICE engines, please, take the time and link to the Wikipedia article that
discusses the effectiveness of HHO generators, Brown's gas generators and similar methods that "boost" efficiency.
